Statement of polar bear population size estimates by polar bear scientists in 1965

Polar bear scientists in 1965 published a consensus statement on population size, with no caveats that these were ‘wild guesses’ or not to be taken seriously. They quoted some of the same authorities that I did when I suggested a plausible baseline figure. Andrew Derocher, Steven Amstrup and others who say there has never been population estimates for the 1960 or 1970s are not defending science, they are lying to protect their ‘polar bears are all gonna die because of climate change’ narrative. No other biologists do this, even those who insist the species they study are at risk from human-caused global warming. You should ask why.

This controversy is why archives like the one I created yesterday are so important: they make it impossible to re-write history as some insist on doing:

Archive of IUCN Polar Bear Specialist Group status and meeting reports back to 1965

The IUCN/SCC Polar Bear Specialist Group have recently modernized their website, which apparently required them to remove all meeting reports and status documents going back to 1968. Since I had downloaded all of them for my own research, I have archived them here for anyone wishing to assess the accuracy of statements made by PGSG members about what they did or said in the past, or to understand the history of the organization. I did something similar a few years ago regarding the administrative reports used in 2007 to support the decision to list polar bears as ‘threatened’ under the US Endangered Species Act (ESA), which disappeared from the US Geological Survey website: they can now be found here.

Fact checkers defend activist scientists because they agree with them not because they are right

The so-called fact-checkers are out again trying to insist one side of a scientific debate is wrong and another is right because they happen to agree with one side. That’s advocacy, not science.

Here are some facts (check the links provided for additional references):

Promoters of polar bear catastrophe in Hudson Bay gloss over recent good ice conditions

Hudson Bay has been oddly slow to freeze this year, which has led to a predictable bit of hand-wringing from certain biologists reiterating prophesies of polar bear population collapse. However, since 2009, the last time that freeze-up was anywhere near this late was 2016. In other words, far from this years’ late freeze-up being a picture of ‘the new normal,’ conditions in 2021 are actually unusual compared to the last twelve years.

Perhaps the last bear leaving Cape Churchill for the sea ice, 4 December 2021.

Moreover, considering that 2021 fall ice formation for the Arctic in general is well ahead of 2016 (and every year since, except 2018), it’s hard to see why human-caused global warming caused by ever-increasing CO2 emissions explains the slow freeze-up of Hudson Bay. Timing of Hudson Bay freeze-up has always been highly variable from one year to the next (Castro de la Guardia et al. 2017: Fig. 3, copied below). The average freeze-up date in the 1980s was 16 November ± 5 days, while from 2005-2015 this had shifted about a week to 24 November ± 8 days (Castro de la Guardia et al. 2017:230). This year freeze-up was later than usual but last year and the three years before that the ice froze as early as it did in the 1980s. Cue the zombie apocalypse.

UPDATE 11 December 2021: see chart below from Andrew Derocher on the position of tagged WH bears at 10 December.

Higher than average Svalbard sea ice extent in November 2021 has implications for birth of cubs

Early last November, sea ice around Svalbard was the lowest it had been since 1967 and pregnant females were simply unable to den on the eastern islands of the archipelago and instead had to make their dens and give birth in the pack ice or the Franz Josef Land archipelago further east, as they have done before. However, the ice is back this fall with a vengeance: even Hopen Island in the south of region was surrounded by ice well before the end of the month but whether it will attract a few pregnant females remains to be seen.

Results of polar bear health monitoring in the spring of 2021 indicated the bears are doing just fine after last year’s low ice levels. Despite this evidence, a single bear photographed killing a reindeer in August 2020 was falsely blamed on climate change. The narrative never seems to change.

Polar bear habit more extensive in most areas of the Arctic compared to previous years

Mid-November is half-way through the Arctic fall season (October-December) and polar bear habitat is expanding slowly. Here’s a look at fall conditions compared to previous years, so you can see where bears may still be ashore and fasting (i.e. Hudson Bay and southern Foxe Basin) and where others have already resumed feeding.

‘Already too late’ to save Churchill polar bears claim a false NY Times climate change cliché for COP26

Not only is it prime polar bear viewing week in Churchill, Manitoba but it’s the week of the 26th international elite COP climate change gab-fest: every media outlet on the planet is eager to promote climate catastrophe talking points.

Hence totally expected that the New York Times would print someone’s unsupported claim that the polar bears of Churchill (part of the Western Hudson Bay subpopulation) are on the verge of extirpation due to lack of sea ice and other similar nonsense. Also not surprising to find that Canadian government biologist Nick Lunn used the occasion to again offer unpublished and misleading data to a reporter. However, this time it’s good news meant to sound like an emergency: if correct, the data he shared indicate polar bears are heavier now than they were in the 1990s and early 2000s.

Global population size estimates for polar bears clash with extinction predictions

How many polar bears are there in the world? This was the primary question the International Union for Conservation of Nature (IUCN) had for the newly-formed Polar Bear Specialist Group (PBSG) back in 1968. Assessing the species global population size was part of the group’s mandate ahead of the 1973 international treaty to protect polar bears from wanton overhunting. For decades, this was an important objective for the scientists that made up the group.

However, about 15 years ago that goal disappeared. I contend it was abandoned because it had become incompatible with the PBSG claim that polar bears are ‘Vulnerable’ to extinction due to human-caused global warming. The group now insists that global population estimates cannot be used to determine if numbers have gone up or down: a Catch-22 that prevents public and scientific scrutiny. This is why they push back so hard when anyone suggests that global polar bear numbers have increased.

Fact checkers fail to refute polar bear number increases despite extensive ‘expert’ rhetoric

There’s seems to be something about polar bears that really sets off the climate change fact-checkers. Mention that the situation for the bears is not quite as dire as we were told they would be 15 years ago and they can’t wait to sink their teeth in.

In early September this year, an Australian a woman I’ve never heard of gave a lecture to students at her former girl’s school and in the process made some critical remarks about Al Gore’s ‘An Inconvenient Truth’. Gina Rinehart said, among other things:

“I’d heard that senior school students in a previous headmistress’s time, were having to watch … An Inconvenient Truth. Catchy title, but sadly short on delivery as far as truth is concerned, e.g. the sad loss of polar bears, when actually their numbers have increased…”

The folks who ‘fact-check’ at the Australian Broadcasting Corporation (ABC) seemed to feel that Ms. Rinehart needed to be taken down a peg for the temerity of that remark, perhaps as it afforded an opportunity to take me down along with her: it seems some things I’ve said or published over the last few years were identified by her office as the source of her remark that polar bear numbers had increased.

In a long-winded essay of more than 2,500 words published yesterday (26 October 2021) the fact checkers provide one of the best examples yet of how convoluted is the official answer to the question: have overall polar bear numbers declined or increased over time? They interviewed a number of experts from the Polar Bear Specialist Group (PBSG) who had a lot to say but claimed it is impossible to address the global population issue.

Sadly, the question of how many polar bears exist today compared to decades ago is unnecessarily complicated and messy, as I discovered years ago. I dealt with this topic in my latest book, The Polar Bear Catastrophe That Never Happened, so for now I’ll just quote a bit from one of the chapters and let you decide for yourselves if the experts quoted by the ABC fact-checkers have a strong enough case to say without question that Rinehart was wrong. For example, you might ask why the PBSG experts used the estimate generated for the Kara Sea subpopulation of about 3,000 bears compiled by Russian researchers (Matishov et al. 2014) for their official IUCN 2015 assessment (Wiig et al. 2015; Regehr et al. 2016) but didn’t include that number in this ‘fact-check document – or why they similarly used an estimate of 2,000 for East Greenland for the 2015 assessment but provide no number for this ‘fact-check’. I’ll probably have more to say later.

No signs of a climate emergency for W. Hudson Bay polar bears this year ahead of UN climate meeting

I’ve been told that another complete aerial survey of the Western Hudson Bay polar bear subpopulation (from the Nunavut to Ontario boundaries) was conducted in August this year and that the bears have been hanging out further south than usual. It will be years before the results of the population count are published, of course (especially if it’s good news) but my contacts also say virtually all of the bears are in great condition again this year.

This is significant because W. Hudson Bay bears are one of the most southern subpopulations in the Arctic (only Southern HB bears live further south) and older data from this region is being used to predict the future for the entire global population based on implausible model projections (Molnar et al. 2020). And scary predictions of future polar bear survival are often taken to be proxies for future human disasters (see ‘Polar bears live on the edge of the climate change crisis‘), a point that some activists will no doubt make in the coming weeks, as the long-awaited UN climate change bash #26 (COP26) gets underway in Glasgow, Scotland on October 31.
